Unmanned space station resupply spacecraft being developed to resupply the planned Chinese Space Station, which as of 2011 was not due to be completed until 2020.

The preliminary designs looked to use an extended version of the pressurized module of the Tiangong space station forward, with a new larger-diameter service module aft, which was evidently fitted with tanks for resupply of liquids and gases required for station operations (propellants, water, oxygen).
